Hello,
I am trying to use the cURL C++ API for TFTP file transfers. I am using
curlpp-0.7.0
and curl-7.16.2 libraries. I get an error indicating No URL is set! I
have
included the a snippet of code below followed by output. Any help would
be greatly
appreciated.
**************************************
size_t Tftp::tftpFRead(void* buffer, size_t size, size_t nitems)
{
printf("tftpFRead: size = %d nitems = %d ", size, nitems);
return (0);
}
int Tftp::put(const char* pLocalFileP, const char* pRemoteFileP)
{
TftpFile tftpFile = {const_cast<char*>(pLocalFileP), NULL};
/**
* Get TFTP handle and test for proper initialization.
*/
cURLpp::Easy curlTftpHandle;
CURLcode curlError = CURLE_OK;
string url;
try
{
/**
* Indicate to cURL this is an upload operation.
*/
curlTftpHandle.setOpt(new cURLpp::Options::Upload(true));
/**
* Indicate to cURL the URL to use for the transfer.
*/
url = url + URL_SCHEME + pAddressM + ":" + pPortM + "/" +
basename(const_cast<char*>(pRemoteFileP)) + ";" + pModeM;
printf("URL: %s\n", url.c_str());
curlTftpHandle.setOpt(new cURLpp::Options::Url(url.c_str()));
/**
* Indicate to cURL the callback function to use for the
transfer.
*/
curlTftpHandle.setOpt(cURLpp::Options::ReadFunction(cURLpp::Types::ReadF
unctionFunctor(tftpFRead)));
/**
* Send the file to TFTP server.
*/
curlTftpHandle.perform();
}
catch ( cURLpp::LogicError & e )
{
printf("The following is a logic error: ");
std::cout << e.what() << std::endl;
}
catch ( cURLpp::RuntimeError & e )
{
printf("The following is a runtime error: ");
std::cout << e.what() << std::endl;
}
return (curlError);
}
**********************************************
OUTPUT BELOW:
Tftp constructor: IP Address = easy Port = 69 Transfer Mode = mode=I
URL: tftp://easy:69/JOHNNY;mode=I
The following is a runtime error: No URL set!
